- the remote control device 200 When the remote control device 200 does not receive the vibration sensing mode signal, the remote control device 200 is located inside the vehicle 100 . Thus, the operation mode of the remote control device 200 is changed to the general mode so that the remote control device 200 can be maintained in active status (S 170 ).
- the general mode refers to a mode in which the vibration sensing mode is in inactive status and the remote control device 200 operates in active status continuously.
- the remote control device 200 may receive LF signals from the vehicle 100 continuously.
- vibration of the remote control device 200 is not detected, and the operation mode of the remote control device 200 may be continuously maintained in the inactive mode (S 180 ).
- the operation mode of the remote control device 200 may be changed to the active mode for a predetermined amount of time (S 150 ).
- the remote control device 200 which is in a state in which it is able to receive the LF signals from the vehicle 100 , may request authentication while performing communication with the vehicle 100 .
- the predetermined amount of time may be set to various amounts according to the user's environment.
- the second signal having the same characteristics as those of the first signal refers to a signal including information about the operation mode of the remote control device 200 generated based on the current location of the remote control device 200 .
- the remote control device 200 when the remote control device 200 is located outside the vehicle 100 , the remote control device 200 changes the operation mode to inactive status according to the signal received from the vehicle 100 , and only when vibration of the remote control device 200 is sensed does the remote control device 200 wake up and perform communication with the vehicle 100 only for the predetermined amount time so that power consumption of a battery (not shown) can be reduced.
- FIG. 8 is a block diagram of a portion of an additional configuration of the vehicle 100 according to embodiments of the present disclosure.
- the vehicle 100 may include a body 110 and a remote control device 120 .
- the body 110 may include a first controller 111 configured to control various devices of the body 110 , a first sensor 112 configured to sense a current location of the remote control device 120 , and a first communication unit 113 configured to transmit/receive signals to/from the remote control device 120 .
- the remote control device 120 may include a second controller 121 configured to control operations of elements of the remote control device 120 , a second sensor 122 configured to sense the user's touch and vibration of the remote control device 120 , and a second communication unit 125 configured to perform communication with the first communication unit 113 .
- the remote control device 120 of FIG. 8 has the same elements and the same operating principle of those of the remote control device 200 illustrated in FIG. 5 . Thus, hereinafter, descriptions of the remote control device 120 of FIG. 8 will be omitted, and only the body 110 will be described.
- the first sensor 112 may sense a current location of the remote control device 120 and may transmit the sensing result to the controller 111 .
- the first sensor 112 may transmit the sensing result to the first controller 111 . Subsequently, the first controller 111 may transmit a first signal including a vibration sensing mode signal to the first communication unit 113 .
- the first sensor 112 may include various sensors and devices for sensing the current location of the remote control device 120 .
- the first controller 111 may control elements included in the body 110 .
- the first controller 111 may be implemented with a memory (not shown) for storing data on an algorithm for controlling operations of the elements inside the body 110 or a program for executing the algorithm, and with a processor (not shown) for performing the above-described operation using the data stored in the memory.
- the memory and the processor may be implemented using separate chips.
- the memory and the processor may be implemented using a single chip.
- the first communication unit 113 may perform communication with the second communication unit 125 of the remote control device 120 .
- the first communication unit 113 may transmit the first signal generated in the first controller 111 and the second signal to the second communication unit 125 .
- a method of performing communication between the first communication unit 113 and the second communication unit 125 is the same as a method of performing communication with the vehicle 100 using the communication unit 210 in FIG. 5 , and thus, descriptions thereof will be omitted.
- FIG. 9 is a view for explaining a relay attack in which a relay attack is performed using a plurality of relay devices.
- the LF signal transmitted from the vehicle 100 may be transmitted to the remote control device 200 via the first relay device relay 1 that is located within the LF signal transmission range of the vehicle 100 and is located within an LF signal transmission/reception range of the remote control device 200 .
- a second relay device relay 2 is located within the LF signal transmission range of the vehicle 100
- a third relay device relay 3 is located within the LF signal transmission/reception range of the remote control device 200 .
- the second relay device relay 2 transmits the LF signals transmitted from the vehicle 100 to the third relay device relay 3
- the third relay device relay 3 transmits the LF signals to the remote control device 200 so that the LF signals can be transmitted to the remote control device 200 from a long distance.
- the remote control device 200 which is located within the RF signal transmission/reception range of the vehicle 100 , transmits the RF signals to the vehicle 100 so that an authentication procedure is abnormally completed, thus compromising the security of the vehicle 100 .
- the remote control device 200 may perform external communication only when the user uses the remote control device 200 and does not perform external communication when the user does not use the remote control device 200 .
- the relay attack illustrated in FIG. 9 can be prevented.
- the operation mode of the remote control device is changed according to the current location of the remote control device so that, when the user is not using the remote control device (e.g., key fob), the operation mode is changed to an inactive mode, and the relay attack can be prevented in advance.
- the remote control device e.g., key fob
- an operation mode is changed according to a current location of the remote control device so that power can be efficiently used in the remote control device car theft such as a relay attack can be prevented in advance.
